Prosecution’s star witness in Percoco trial mocked disabled pal.

Things turned ugly Wednesday at the corruption trial of ex-Cuomo aide Joseph Percoco, as email evidence showed him and the prosecution’s tainted, star witness cruelly mocking a co-defendant’s affliction.

Day four of ex-lobbyist Todd Howe’s cross-examination saw him confronted with computer correspondence in which he and Percoco viciously joked about the temporary facial paralysis suffered by Peter Galbraith Kelly Jr., who at the time was afflicted with Bell’s palsy.

The mean-spirited exchange began with an April 23, 2015, message from Howe in which he urged Percoco, a former top aide to Gov. Cuomo, to “keep [Kelly] happy….I have two more years of college to cover.”

“No worries. I will take good care of him. Hope he doesn’t look like a monster!” Percoco wrote.

“Bring plenty of napkins u may need to wipe the left side of his mouth!!! Lol….when is the surgery?” Howe responded.

Howe — who’s been jailed since Thursday night over self-incriminating testimony — sheepishly admitted from the witness stand that he had been “making fun” of Kelly, who has since recovered from the nerve disorder.

Kelly is accused of funneling nearly $290,000 in bribes to Percoco in a failed bid to score a deal for his then-employer, Competitive Energy Ventures, to sell electricity to the state Power Authority.

Those payoffs comprise one of two alleged “pay-to-play” schemes by Percoco, who came to court with an Ash Wednesday mark on his forehead, but wouldn’t say what he’s giving up for Lent.

“I have lost patience. The jury has lost patience — at least four hours ago, if not eight hours ago,” she said.

Howe also bristled from the witness stand when another defense lawyer, Steven Coffey, began questioning him about the role of Cuomo’s dad, the late Gov. Mario Cuomo, in the origin of the “Herb” nickname that Howe and Percoco called each other.
